So I setup my dual monitors and typed the script to have my second monitor extend the first. It used to work really well but now, when i turn on my computer and startx, it completely ignores my script and now the monitors mirror images. If i restart the computer and startx again, then it works fine and the first extends the second. This seems like a really trivial problem but it's really annoying. How can I make sure that it works everytime?

Section "Monitor"
Identifier "VGA screen"
Option "Rightof" "DVI screen"
Option "PreferredMode" "1440x900"
EndSection[/code]
I don't think this is the problem. It works when I reboot but does not work when I first start the computer.

This seems unlikely but perhaps if I capitalize the O in "Rightof" it might work.

So apparently sometimes your monitor is called HDMI-0 and sometimes DVI-0. In my experience with RS780/880 chipsets, the output is called HDMI-0 when HDMI audio is enabled. You could either investigate that or add a workaround like this:

I think there might be a problem with detecting drivers. Just now, the driver for my mouse and keyboard seem to not work, the log says that it was not found. Also, eth0 does not start and gives me a message about interface eth0 not existing and that I have not loaded the correct kernel module for my hardware.
